The safety performance of the diamond cup grinding wheel is a quality issue that cannot be ignored because the "tooth loss" caused by production or use directly affects the performance of the product and the personal safety of the operator. In industrial production, diamond cup grinding wheels are dangerous to use. To protect and care for life, manufacturers and users are increasingly concerned about their own safety.
Factors affecting the safety performance of diamond cup grinding wheels:
1. The outer scallops of the base are not clean, resulting in poor welding and bonding.
2. The sintering process parameters are not well controlled, the sintering temperature is low, the "under-burning" makes the welding unstable, and the matrix itself has low strength and is fragile.
Measures to improve the safety performance of diamond cup grinding wheels:
Optimize the design, use low-oxygen raw material powder; change the outer cylindrical shape of the matrix to "swallow tooth" to improve the bonding strength between the matrix and the matrix.
Optimize the process. The teeth of the base body adopt the "copper plating" process; the cold pressing-hot sintering process; the hot pressing-fusion welding process (ie, the laser welding process). In traditional high-frequency welding, the bonding strength of the weld (especially at high temperatures) is not high enough, and it is easy to fall off when sawing. Laser welding uses a focused laser beam as energy and adopts the mechanism of penetration welding to melt the transition layer and the base of the cutter head to form a firm weld. High welding strength and safety of use are guaranteed even when saw blades and drills are used without cooling water.
